Lost weight and this is bad for once....

Ok so this is probably the only time in my life when I'll say this, but why in the world am I still not putting on weight. Not only am I not putting on weight but I seem to be losing weight! That can't be good for the baby. I've tried everything! I thought it was just cause of the morning sickness that I was losing weight, but I haven't had any in weeks and I now weigh 6 lbs less than I did before I got pregnant! I eat constantly! I don't get it! It's like all of a sudden I have Michele's metabolism or something! In a normal situation I'd be thrilled that I'm losing weight and not having to work at it, but with a baby now the size of my hand growing inside me, I'm more than a little worried about this..
